Square Compact Fluorescent Lamps

Energy saving bulbs are available in many different versions. For example, Budgetlight has square compact fluorescent lamps, in which the light is evenly distributed through its square shape. With the square CFL bulbs you have the choice between two sockets. The 2-pin socket works on a conventional ballast. The 4-pin socket works on an electronic ballast. This means that the 4-pin does not need a starter to work and also has a longer life than the 2-pin.
